Banks around the world are on the hook for as much as $70 billion in bond insurance payments if Greece defaults on its debt. But a panel ruled that Greece's plan to restructure its debt should not trigger any insurance payments, at least for now.

It ruled that the Greek bond deal was still being carried out and did not yet constitute a credit event -- but that the question could come up again.
